Semiconductors Lead Stocks Higher

Key Takeaways

  • Semiconductors continue to lead the broader market to new highs.
  • The growing integration and excitement around artificial intelligence (AI) has revitalized demand and optimism for the industry.
  • World chip sales have returned to growth for the first time in roughly 18 months, while the largest chip manufacturer recently forecasted “healthy growth” for 2024.
  • Historically, the return of growth in chip cycles has led to continued upside momentum in both semiconductor stocks and the broader U.S. equity market.

Records have been on repeat for the semiconductor space as the outlook for chip demand continues to improve. The proliferation of spending on AI, coupled with an expected rebound in PC demand and increased chip usage across the automotive industry, have helped offset concerns related to elevated inventories and slowing global growth.

As highlighted in the chart below, the Philadelphia Semiconductor Index (SOX) has rallied to new highs after recently breaking out from a bullish cup-with-handle formation. Momentum indicators, breadth, and volume are further confirming the bullish price action. In terms of upside, a minimum technical-based price objective for the SOX sets up near 5,200 based on the size of the prior formation. Perhaps more importantly, and as illustrated in the bottom panel, semiconductors are also leading this bull market, as the SOX vs. S&P 500 (SPX) ratio chart also broke out to new highs.

Taiwan Semiconductor Manufacturing (TSM) — the world’s largest chip manufacturer and a key supplier to both Apple and NVIDIA — further revived confidence in the space after issuing positive revenue guidance during their fourth-quarter earnings release last week. TSM’s Chief Executive Officer C.C. Wei pointed to low to mid-20% revenue gains (in dollar terms) for 2024 and noted, “Our business has bottomed out on a year-over-year basis, and we expect 2024 to be a healthy growth year.”

The latest data from the Semiconductor Industry Association (SIA) corroborates TSM’s outlook. As illustrated in the table below, worldwide chip sales increased on a year-over-year basis in November for the first time since the summer of 2022.

Global Chip Sales Turn Positive

Given the cyclicality of the global semiconductor market, we analyzed how the SOX performs after each cycle turns positive. Considering semiconductors are also widely regarded as a leading economic indicator given their vast application use across industries, we also included how the broader SPX performed during these positive chip cycle shifts. As highlighted in the table below, momentum in both indexes continued. The SOX outperformed with an average 12-month forward return of 27.7% (eight of the nine periods also posted positive returns during the 12-month period).

An upcycle for semiconductors appears to be underway as the excitement for AI revives demand. The growth story, supported by bullish guidance from the world’s largest chip manufacturer, the recent return to global chip revenue growth, recovering PC sales, and rising demand from the automotive industry, have all helped offset concerns over rich valuations and prior supply gluts. Historically, the start of growth cycles in chips has led to continued momentum for semiconductor stocks and a bullish sign for the broader market.
